I really should read more Luther. We all should. Read, and enjoy:
We who serve the church and hold the teaching office are certainly in a poor and lowly position, measured by the standards of the world against that of other professions. For we usually earn hostility for our labor and suffer not only haughty scorn but even hunger and want, while others are well rewarded and held in the highest esteem. We find, moreover, that for this reason men of superior ability turn away from our office and follow rather those callings which are profitable and respected.
But if you look at this question in the right way, no matter how miserable and despised he may be, the theologian is in a better position than all the teachers of the other professions. For as often as he performs his duty he not only does his neighbor a valuable service, which is superior to all the favors of all other men, no matter how precious and useful they might be; but he also offers to God in heaven Himself the most pleasant sacrifice and is truly called the priest of the All-highest. For everything a theologian does in the church is related to spreading the knowledge of God and to the salvation of men (AE 12, Preface to vol. 1 of Selected Psalms, p. 4).
Who can add anything to that?
